THE CANADIAN ENTOMOLOGIST. 69 



endeavoring to drive a Zygaenid moth (Anatolmis Grotei) off the blos- 

 soms of a large species of Senecio. The moth, which is a sluggish 

 creature at all times, would not fly, but slowly backed round the corym- 

 bose head of flowers, occasionally lifting its front legs in feeble protest. 

 Hesperis followed it, flapping its wings and clawing at it like a cat, till the 

 persecuted moth at last escaped by slipping over the petals, and hanging 

 on the under side. It is probably owing to this restless and quarrelsome 

 disposition that individuals are so soon worn and broken. They vary 

 much in size and in the color of the spots on under side, some being of a 

 deep buff, others a dead white, and others with a trace of frosted silver. 

 I have taken Hesperis just below the timber line, but it is not common at 

 such elevations, nor below 6,500 feet in Colorado." 



Mr. Bruce sent me eggs of this species from Denver, Colorado, which 

 I received 9th July, 1886, and a second lot three days later. The eggs 

 hatched at ten days, and after eating the shells, the larva; went into 

 lethargy. I sent them soon after to Clifton Springs, N. Y., to go in a cold 

 room there, and they were returned 21st March, 1887, nearly all alive. 

 But they came unexpectedly, and a month too soon, and before I could 

 force a plant of violet for them nearly all had died. Of the few survi- 

 vors, one passed 1st moult 20th April, the second 3rd May, the third nth 

 May, the fourth 15th, the fifth 23rd. This larva pupated 6th June, and 

 the imago came out 16th June. Another pupated nth June, but died 

 before imago. The habits of the larvae in confinement are similar to those 

 of Atlantis. The butterfly is figured in Vol. 1, Butterflies of N. America.

Cucullia Hartmanni, n sp. 



Expanse 1.75 inches, length of body .75 inch. General color of fore 

 wings pale gray, so suffused in places with dark gray as to give the wings 

 a moderately dark gray cast, but not so dark as C. intermedia, Spey. 

 Lines black, basal half line only indicated on the costa. T a. line double; 

 the inner part almost imperceptible ; strongly dentate, from its origin pro- 

 jecting obliquely outward to a strong tooth on the fold in the discal cell,
